For an immersed submanifold x: Mm → Sn in the unit sphere Sn without umbilics, an eigenvalue of the Blaschke tensor of x is called a Blaschke eigenvalue of x. It is interesting to determine all hypersurfaces in Sn with constant Blaschke eigenvalues. In this paper, we are able to classify all immersed hypersurfaces in Sm+1 with vanishing Möbius form and constant Blaschke eigenvalues,...
